Assessment of the St. Jude Medical Regent Prosthetic Valve by Continuous-Wave Doppler and Dobutamine Stress Echocardiography

Although the PPM incidence was 6.6%, it was deemed from the data of DSE and clinical symptoms that there were no clinical issues for such cases of PPM in the early and intermediate phases after operation. Particularly, the effectiveness of the 17- and 19-mm valves in patients with a small aortic annulus was demonstrated, confirming the satisfactory functions of the SJM Regent prosthetic valve.
